; Patented June 4, 1907.

To all whom) it may concern.-

Be it known that I, ARTHUR GRANDJEAN, a citizen of the United States of America, residing at San Diego, in the county of San Diego and State of California, have invented new and useful Improvements inBedclothes- Clamps, of which the following is a specification. a

This invention relates to bed clothes clamps designed to prevent the accidental displacement of the bed clothes or covering from a bed.

One object of the invention is to provide a clothes clamp which is readily applicable to the stated purpose, and which is inexpensive of construction and adapted to be conveniently manipulated and to clamp the clothes in an effective manner. v I

Another object is to provide a construction wherein the clamping bars are readily adjustable on and removable from their actuating jaws, and whereinan improved tensioning or adjusting device is provided to force the jaws in clamping engagement.

A still further object is to rovide a construction of clamps which admit of the ready removal of the front clamping bar toafiord greater space in removing and replacing the beddin and also to provide a construction which adapts the parts of the clamp to be inexpensive of manufacture.

With these and other objects in view, the invention consists of the novel construction, combination and arrangement of parts hereinafter fully described and claimed, reference being had to the accompanying drawing, in which Figure 1 is a front elevation of a bed clothes clamp constructed in accordance with m invention.v Fig. 2 is a vertical section of the clamp shown in Fig. 1. Fig. 3 is a front elevation'oi' amodificd form of clamp. Fig. 4.

mentary elevation of the clamp shcwn in is a vertical section of the same.- Fig. 5 is a detail view of the eccentric. Fig. 6 is a frag Figs.'3 and 4.

Referring to Figs. 1 and 2, the numeral 1 indicates bars between which the clothes of 'abed are adapted tobe clamped in order to revent the accidental displacement thereof om the bed. The clamping bars are supported by a plurality of. clamping devices indicated generally by the reference numeral to forcing said jaw toward the jaw 3 holds the same from removal.

In the form shown in Figs-.1 and 2 the clamping bars-consist of flat strips fastened upon the inner faces of the jaws by rivets or equivalent fastenings 1 The lower end of the jaw 3 is provided with a hook or projection 6 to hold and support the lower end 'of the jaw 4, which is adapted to be applied and removed by vertical movement. ture of the removability of the jaws 4 enables the same and the bar 1 carried thereby to be. detached to afford greater space in removing .and re lacing the bedding.

Each compression device 5 comprises a bracket plate 8 which may be integral with the jaws 3 or formed independent thereof ing v9. This bracket plate carries a pair of supporting lugs 10 arranged on opposite sides and projecting in advance of the j aw 3 and perforated for the reception of a pivot pin or screw 11 arranged transversely on the outer side of the jaw 4. The bracket plate carries apertured ears 12 projecting laterally beyond the lugs 10 and designed for the passage of screws orother fastenings to secure the clamping device to one of the side orend rails of a bed or the side'or end of a couch, cot or similar article of furniture. This type of attaching means also permits of the application of the clanip to the spring frames 0 spring cots and spring beds. Disposed This feaand secured thereto by a rivet or like fastenbetween the lugs 10 is an eccentric compris ing a head 13 c arrying an actuating handle 14 and formed in its outer side with a longitudinal groove or recess 15 receiving the pin 11, whereby said eccentric is pivotally mounted thereon. Pairs of projections 16 are formed upon the head on opposite sides of the groove and adjacent the ends of the head, as shown in Fig. 5, which illustrate the eccentric as initially formed and before-it is applied in position. The rear side of the eccentric head is provided with a fiat face-17 to bear directly against the outer face of the jaw 4,; as shown in Figs. -1 and '2, oragainst a boss formed on said jaw, as hereinafter to an upright p into engagement withthe jaw ,4

the bottom or side of the described. When the handle '14 is turned osition the face 17 is brought.

' to force the same toward the companion jaw 3, aswiil be readily understood.

In Figs. 3 and 4 the outer'faces of the aws 3 and 4 are providedwith side strengthening flanges 18,. and the clamping bars 1 are preferably of semicircular form, their outer opposing. faces being curved to clamp the clothes without injury. These bars are held between retainingfingers v19iormed onthe jaws, vwhichzfingers extend over. and grip the a curved faces. The bars are insertible; within.v and vwithdrawable from the fingers by alone,

gitudinal sliding rnovementf and.-.,are, hence adapted-to be readily removed and ad usted anyv position along bed .to which the clamping device is applied A When they-j aws are cast these fingers maybesoiormed that they maybe bent to grip the clamping bars with. any desired. degree ofiorce. The Qjawv to clamp the clothes at 4* is arranged and supported in this.-.embdi-'v ment f the invention in the same .manner; in which. the jaw.4 in "FigsLL' and 2 is sup-- ported, and arranged, and .is consequently.
